Abstract
Viene descritto un catalizzatore per produrre olefine terziarie partire da alchil-ter-alchil-eteri costituito da silice modificata con l'aggiunta di allumina in quantità compresa fra lo 0,3 e l'1% in peso rispetto alla silice, il quale viene ottenuto mediante un procedimento consistente essenzialmente in una impregnazione di una silice con una soluzione di sali d'alluminio, cui segue un essiccamento e una calcinazione, essendo poi il materiale ottenuto sottoposto ad un trattamento di purificazione con soluzioni acquose acide o con soluzioni acquose che liberino acidità per decomposizione termica, cui segue un lavaggio, un secondo essiccamento ed una seconda calcinazione.
